17 Kronprinzenstrasse, Essen-on-the-Ruhr,

Prussia, German Empire,) have invented a new and useful Improved Device for Preventing Seasickness and Similar Symptoms on Shi s, Vehicles, and the Like, of which the fol owing is a specification.

The resent invention has for its object means for preventing seasickness and similar symptoms on ships, vehicles, lifts, &c.

When a shi pitches and tosses, what passengers usual y find most unpleasant is the reversal of the movement of the vessel, the feeling experienced increasing in unpleasantness with the suddenness of this reversal. Attempts to render the transition from one direction of movement to the other less disagreeable by the employment of air-cushions or yielding seats for the passengers have been unsuccessful, because it is not possible to lengthen the transition period by their means. In order to obtain such a retardation of the period of transition from one direction of movement to the other, in accordance with the present invention an air-cushion is also used for the seat; but this cushion is connected with an air-reservoir the walls of which are not loaded from the outside with the weight of the person using the seat. The air-reservoir is in communication with the air-cushion by means of a narrow opening, such as a fine tube or the like, so that the transference of the air from cushion to reservoir, or vice versa, can only take place slowly.

Two methods of carrying the invention into practice are illustrated in the accompanying drawings.

In the constructional form shown in Figure 1 an air-cushion I is arranged upon the seat of the chair, while beneath the chair an air-reservoir I I is suspended in such a manner that its walls are not acted upon from the outside by the weight of the person using the chair. The cushion I is connected with the reservoir I I by means of a tube 12, which is of small diameter in proportion to the contents of the cushion and reservoir. A cook 13 or the like is provided on this tube for regulating the passage of the air from the cushion to the reservoir, and vice versa.

In the constructional form represented in Fig. 2 the chair is combined with a frame 4 5 6, on which rollers 1 2 3 are provided and slide in vertical guides 16 17. The frame is connected by struts 7 8 or the like with the cover-plate of a boX or socket 11, open below. A socket 18, open above, enters this socket 11, its bottom resting upon a nut which is screwed upon a rod 15, suspended from the deck or roof beam or the like. The air-cushion I is arranged between the two sockets, and in this instance it consists of a number of separate pipes or hose connected one with the other by openings. Upon a bracket 14, mounted on the socket 11, the air-reservoir I I is arranged. In this case also the reservoir communicates with the cushion I through a tube 12, provided with a' cock 13. The ,air-cushion 1, arranged between the two sockets 11 and 18, permits the socket 11 to move slowly relatively to the socket 18, whereby the air passes slowly from the cushion I through the tube 12 into the air-reservoir.

In order to diminish not only the unpleasant vertical movements, but also lateral or oblique movementssuch as the rolling of a ship, the swaying of a vehicle, or the like-in addition to roviding air-cushions for the seat or the ike, the back and sides, arms, and foot-rest may each be provided with an air-cushion I and air-reservoir I I. Any other fluid may be employed in the cushions and reservoirs in lace of air.

What I claim, and desire to secure by Letters Patent of the United States, is

1. In an ap aratus for preventing seasickness and simifar symptoms the combination of a chair or seat with an air-cushion loaded by the weight of the person using the seat, an air-reservoir and connection of the air-cushion withthe air-reservoir, essentially as and for the purpose described.

2. In an apparatus for preventing seasickness and simi ar symptoms the combination of a chair or seat with an air-cushion loaded by the person using the seat, an air-reservoir connection between the air-cushion and the air-reservoir and means for regulating the passage of the air through such connection from the air-cushion to the air-reservoir and back, essentially as and for the purpose described.

3. In an apparatus for preventing seasickness and similar symptoms the combination 5 In testimony whereof I have hereunto set of a chair or seat With a number of pipes or my hand in presence of two subscribing Wit- IO hose communicating withh each otherh by nesses.

openin s and formin to et er an air-cus ion loaded by the persoi using the seat, an air- HERMANN RINNE' reservoir and connection between the air- Witnesses: cushion andthe air-reservoir, essentially as WILLIAM EssENWEIN, and for the purpose described. GERHARD HEIDER.
